195 I walked into our anniversary party with a man my husband had never met. He laughed in front of everyone and asked,

The scream of the klaxon felt like hot needles driven straight into my skull. Red emergency beacons pulsed across the riveted girders of the roundhouse, washing Julian Croft’s tailored cashmere coat in the color of fresh arterial blood.

He didn't move. He stood there beside the polished brass rail of his private Pullman car, holding his silver pocket watch in the palm of a gloved hand, the picture of aristocratic serenity amid the wail of mechanical death.

"Five minutes and twenty seconds, Nina," Croft said, his cultured voice cutting through the roar of the alarms like a blade through dry parchment. "You sign the transfer of the Raton easement right now, and my dispatch center in Omaha overrides the automated line blocks. They'll throw the dead-weight retarders at the switch point above the canyon. Refuse, and forty thousand barrels of Bakken crude punch through the severed timbers of Bridge Seven and rain liquid fire straight down into the Trinidad valley. Every house, every school, every child sleeping within three miles of this depot will burn."

My hands shook, but not with fear. They shook with the cold, crystalline fury that had kept my father alive through thirty winters on this unforgiving mountain.

"You blew the trestle," Jonah said. His voice was a flat, terrifying whisper. He hadn't lunged for Croft. He hadn't drawn back a fist. Instead, he had planted his work boots wide, his shoulders squared, every sinew under his grease-stained canvas coat coiled like a steel cable under maximum load. "You placed thermite charges on Bridge Seven before your jet even touched down in Denver."

"Prudent risk management, surveyor," Croft murmured, checking his watch again. "A good financier hedges every contingency. You have five minutes. The pen is on my desk inside."

"Mack!" I shouted, turning my back on the billionaire.

Croft’s eyebrows twitched, the very first crack in his porcelain mask. To a man who owned senators and steamship lines, being ignored was an intolerable insolence.

"Talk to me, Mack!" I sprinted across the oil-slicked concrete to the main dispatch panel, where Mack was slamming switches with calloused, trembling hands.

"The train is manifest seven-zero-four!" Mack yelled over the shriek of the seismic sensors. "Two locomotives, ninety tank cars carrying pressurized crude! Crew bailed out two miles back when they lost dynamic brakes on the steep grade—Croft's saboteurs cut the brake lines at the summit! The speed is up to seventy-two miles an hour! If it hits the blown center span of Bridge Seven, forty cars will launch into free-fall down the gorge, straight onto the municipal water plant and the lower residential district!"

"What about the runaway switch at milepost eighteen?" I demanded, leaning over the grease-penciled topographic map pinned to the wall.

"Locked out!" Mack spat, wiping sweat and snow from his gray beard. "Croft’s boys jammed the mechanical points with hardened steel wedges! Even if I throw the switch remotely, the signal won't engage the points!"

Jonah was beside me in two long strides. His eyes raked the schematics, not as a dispatcher, but as an engineer who had surveyed every contour of this dirt with his own boots.

"The old quarry spur," Jonah said, his finger slamming onto a faint, yellowed line drawn in David Taylor’s hand thirty years ago. "Milepost twenty-one. It’s an uphill switchback built in nineteen-eighty-four to haul granite riprap for the dam. It climbs an eight-percent grade into the shale face. If we route that train up the quarry spur, gravity will kill seventy miles an hour of momentum in eight hundred yards."

"That spur was decommissioned twenty years ago!" Mack shouted. "The manual switch is frozen solid under four inches of ice, and the hand-throw lever is padlocked under a municipal condemnation order!"

"Then we break the lock," Jonah said, turning toward the open bay doors where the blizzard was howling into the yard. "And we throw the iron by hand."

"Jonah, you can't get there in four minutes!" I grabbed his arm, my fingers digging into the heavy canvas of his jacket. "The road to milepost twenty-one is buried in snow!"

"We don't take the road," Jonah said. He looked down into my eyes, and in that split second, the noise of the sirens and the howling storm seemed to fade into utter silence. His hand came up, framing my cheek, his palm rough and warm against the biting mountain chill. "Your father built that maintenance speeder with a snowplow welded to the nose, Nina. We take the low-clearance rail car. We run the bypass."

"I'm coming with you."

"Nina—"

"I am Chairwoman of this railroad," I said fiercely, my voice leaving no room for argument. "And David Taylor didn't leave this valley to cowardice. We go together."

Croft’s cold laugh drifted across the concrete floor. "A suicide run on an antique handcar? How touchingly cinematic. You'll die in the snow before you reach the switch, Taylor. Sign the paper and live."

I didn't even look at him. "Mack, clear the bypass line. Mateo, get the gas torches from the shop! Move!"

Mateo and four young apprentices moved with lightning speed, shoving aside Croft’s two armed security guards as if they were nothing more than scarecrows. Mateo hefted two heavy oxygen-acetylene bottles onto the flatbed of our custom four-wheeled inspection speeder, while another apprentice primed the two-stroke engine.

With a sputter and a deafening, two-stroke pop, the maintenance speeder roared to life. Jonah jumped into the driver's cage, hauling me up beside him.

"Three minutes and forty seconds!" Mack screamed from the door, his hand gripping the dispatch mic. "May God ride with you both!"

Jonah shoved the throttle forward. The steel wheels shrieked against the icy rails, spitting blue sparks into the darkness, and we shot out of the warm depot straight into the teeth of the blizzard.

The cold was an immediate, brutal fist against my face. The wind ripped down from the Raton peaks at fifty miles an hour, driving stinging needles of sleet into our skin. The yellow beam of the speeder’s single headlight pierced barely ten feet into the whiteout.

Ahead of us, through the shuddering metal frame of the speeder, I could feel the rail singing.

It was a terrible, terrifying vibration. It wasn't the rhythmic thrum of normal freight; it was a rhythmic, violent thudding that traveled through miles of solid steel—the sound of ten thousand tons of unguided steel and crude oil hurtling down an icy mountain slope.

"There's the quarry switch!" Jonah yelled through the roar of the wind, pointing into the blinding darkness.

Two hundred yards ahead, where the single mountain track skirted a narrow ledge above the frozen Purgatoire River, a rusted steel switch-stand emerged from the snowdrifts like a tombstone.

Jonah killed the throttle and yanked the mechanical brake. The speeder skidded violently across the iced rails, slewing sideways before slamming into the trackside snowbank.

We threw ourselves out into the waist-deep snow.

"Torch!" Jonah yelled.

Mateo had already clamped the striker to the nozzle. I caught the flint striker, dragged it across the tip, and a brilliant, hissing tongue of blue-and-orange flame burst into the night.

"Two minutes!" I screamed, checking the glowing red numbers on my wristwatch. The mountain behind us seemed to groan. High above, through the swirling clouds, twin locomotive headlights pierced the darkness like the eyes of an oncoming leviathan. The air horn was dead, but the deafening roar of grinding flanges against frozen rail was loud enough to vibrate the enamel in my teeth.

Jonah dropped to his knees in the slush, directing the searing cone of flame straight at the rusted iron padlock holding the switch points captive. The ancient brass lock hissed, weeping boiling water, then glowed dull orange.

"Hit it!" Jonah barked, tossing the torch into the snow.

He seized a forty-pound track maul from the back of the speeder. He swung with the full, devastating power of his broad shoulders.

*CLANG!*

The iron padlock shattered into three jagged fragments.

Jonah grabbed the long, heavy mechanical throw lever. He planted his boots against the tie and hauled back with every ounce of strength in his body.

The switch didn't budge.

"It's iced between the points!" I yelled, dropping to my knees and clawing frantically at the packed gravel and ice wedged between the switch-rail and the main rail. The jagged metal tore through my leather gloves, biting deep into my palms, but I felt no pain—only the desperate, screaming urgency of a town full of innocent lives hanging on two inches of steel.

Above us, the high headlight of the runaway train burst around the upper curve at milepost nineteen. It was a terrifying wall of black steel, roaring at seventy miles an hour, throwing a blinding spray of snow and glowing embers thirty feet into the night sky. The ground beneath our knees bucked violently.

"Together, Nina!" Jonah shouted, his hands clamping over mine on the icy throw handle. "On three! One... two... THREE!"

We threw our combined weight backward into the snowdrifts.

With a sickening, metallic screech that sounded like tearing bone, the ice shattered. The points snapped over, locking into the quarry siding with a heavy, definitive *THUD-CHUNK.*

"DOWN!" Jonah screamed.

He wrapped his entire body around me, throwing me flat into the frozen ditch just as the runaway manifest bore down on the switch.

What followed was an apocalypse of sound.

The two six-thousand-horsepower diesel engines hit the diverging switch at over sixty miles an hour. The outer rails screamed in agony, steel shaving off steel in a blinding shower of molten white sparks. The lead locomotive reared upward like a wounded beast, its massive steel wheels lifting six inches off the ballast before the sharp banking of the quarry spur dragged it violently to the right.

Ninety black tanker cars followed, whipping through the turn like the tail of a dying dragon.

Instead of plunging straight down the main line toward the broken trestle and the sleeping streets of Trinidad, the runaway train shot upward into the abandoned granite cut. The brutal eight-percent incline immediately began clawing at the train's momentum.

One thousand yards up the dark mountainside, the lead engine plowed into a hundred-foot embankment of loose quarry shale with a hollow, concussive *BOOM* that shook the snow from the pine trees for miles around.

Then, silence fell.

The train had stopped. The tankers held. Not a single car had ruptured. Not a drop of oil was burning.

Jonah lifted his head from the snow. His face was white with frost, his lips blue, his hair plastered against his forehead. But his gray eyes, as they found mine in the cold mountain light, blazed with an untamed, triumphant fire.

"We did it," he whispered, his chest heaving against mine, his arms still locking me protectively against the frozen earth. "Nina... we did it."

I couldn't speak. I reached up, my torn, bleeding fingers tangling in the collar of his jacket, and pulled him down until his forehead rested against mine.
